| Abstract: | It is important to study 58X wheel tolerances of engine speed sensor for misfire diagnostics based on crankshaft speed fluctuation. This paper studies the influence of 58X wheel tolerances on recognizing misfire based on Chery 447F engine. The remedy strategies for 58X wheel tooth learning in misfire detection are studied and optimized. |
